Question

1.Write one solution of the equation

2.Find the measure of an angle which is 30◦ more than its complement.


3.Simplify (25)1/3X(5)1/3.


4.An exterior angle of a triangle is 120◦ and its two interior opposite

angles are equal. Find each of interior angles. x-2y=4.​

Answer 1

Answer:

1) what's the eqn? x-2y=4?

then one soln could be (0,-2)

2) let the angle be x

x + 30°= 180°

x = 180° - 30°

x = 150°

3) Using law of exponents

(25)^1/3 × (5)^1/3

= (25×5)^1/3

= (125)^1/3

4) By exterior angle formula,

a + b = 120

since a and b are given to be equal

2x = 120

x = 60°
